I made an limitless runner-like sport

I developed an Android sport – "Spin Blitz – Countless runner". You destroy as many enemies as you possibly can earlier than inevitably shedding, then use the sources you bought to improve and do higher subsequent time. Because the title implies, it's an limitless runner.

I'm at the moment a bit caught in making the sport higher so I might significantly respect any suggestions.
